THRASHlNG-MACHINE ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 479,156, dated July 19, 1892.

Application filed April 26, 1892. Serial No. 430,694. (No model.)

To all whom it may concern.-

Be it known that I, ALBERT REASON, a citizen of the United States, residing at Pinckney, in the county of Livingston and State of Michigan, have invented a new and useful Thrashing-Machine Attachment, of which the following is a specification.

This invention relates to straw-carrier attachments for thrashing-machines and it has for its object to provide an improved carrier and stacker attachment for thrashing-machines which is directly connected with the thrasher at the delivery end thereof, so as to receive the straw from the machine and carry the same to the point of attachment.

To this end it is the main object of this invention to provide an improved swinging attachment which may be adjusted at any angle to either side of the thrasher and to any point of elevation, according to the height of stack, and also to provide special and improved means for operating and adjusting the carrier upon the thrasher.

With these and many other objects in view, which will readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated, and claimed.

In the accompanyingdrawings, Figure l is a perspective view of a thrashing-machine provided with a swinging carrier attachment constructed in accordance with this invention. Fig. 2 is a vertical longitudinal sectional View through the attachment and the rear end of the thrashing-machine. Fig. 3 is a vertical transverse sectional view of the same. Fig. 4 is a detail in perspective of the rotating table-frame and the carrier-frame carried thereby. Fig. 5 isan enlarged detail viewof the universal shaft-coupling.

Referring to the accompanying drawings, A represents a thrashing-machine of any improved construction and provided with the rear top deck 13, projecting beyond the strawdelivering end of the thrasher and above the under separating-shoe 0, located in front of the ordinary fan of the thrasher.

Mounted to oscillate or swing upon the deck B and over the rear end of said deck is the swinging table-frame D, provided at the inner ends thereof with the transverse bolster d, to which is fixedly secured the pivotbolt E, projecting through and journaled in the deck B, so as to provide means for allowing the said table-frame to freely oscillate in its swinging movement upon the top of said deck.

Securely keyed to the pivot-bolt E, directly under the bolster d, is the horizontal gearwheel F, from which motion is imparted to the swinging table-frame to oscillate or swing the attachment when desired. The gear- Wheel F is inclosed within the iuclosing casing f, entirely inclosing the top and outer rim of the gear-wheel, so as to securely hold the said wheel in position, and therefore the entire table-frame, fixedly upon the top of the deck B, so that the same will evenly oscillate back and forth over the deck upon which the same rests and is supported, so as to relieve the frame from the weight of the carrier supported thereby.

The inclosing casing f is provided in one side thereof with the opening f, within which is jourualed one end of the adjusting-shaft G. The saidshaft G is suitably journaled in the top frame or deck of the thrasher and held off from one side of the same, so that it may be operated at the proper time by suitable means for turning the same. The said shaft is provided at its outer end on one side of the thrasher with the wheel g, from which the shaft receives its motion by hand, while the other end of the shaft within the opening f in the casingfis provided with a screw g, meshing with the rim of the gear-wheel F, and thus serving not only to rotate said wheel to swing the frame, but also holds said frame in its adjusted position.

Secured to the opposite outer ends of the swinging table-frame D are the opposite depending supporting standards or arms H, to the lower ends of which are secured the opposite parallel inwardly-extending pivot-arms h, which are inclined downwardly, so as to project under the separating-shoe C and sufficiently under the straw-deliveringend of the thrasher, so as to place the lower end of the straw-carrier frame I in a position to receive the straw from the thrasher.

The straw-carrier frameIis of the ordinary construction and is provided with the usual endless belt 2', working over the upper and be adjusted and swung to either side of the thrasher in any direction and still have its inner lower end under the delivering end of the machine, but also that the said carrier can be adjusted to any height or angle desired, according to the height of stack.

Secured to the under side of, the carrierframe I and near the outer end thereof are the opposite eyes or guides J, through which pass the carrier-frame adjusting-cordj, passingunder said outer end of the. said frame I.

The said adjusting-cord j is fastened at one end, as at j, to the body of the. thrasher at one side thereof and passes from such point through the eye 7' secured to the topof the thrashcr. From the eye 3' the adjusting-cord extends to the center and top of the. bolster d and between the guide pulleys or rollers K, secured to the top and centerof said bolster, thence toone sideof andunder-the outer end of the :frame I, as, described, and is returned backtthrough the central guide pulleys or rollersK and upontheopposite sideof the thrashing-machine. The free end of the adjusting-cord j is led from the central guiderollers over the offstanding guide pulley or wheel K, supported at one side of thedeck B direetly opposite the guide or eye 3' and said'cord belowthe pulley orwheel K- is connected to the winding-drnm K upon one side of the thrashing machine body, and which provides means for-shortening or lengthening the. cord to raise and lower the outer end of the stacker-frame I to adjust the angle or pitch of the same. ing the opposite portions of the adjustingcord upon the top and center of the tableframe bolster the; saidcord can beeasily lengthened or shortened without interferonce from the swinging. table-frame in any position that the; same may be turned. In order to prevent the opposite portions of the adjusting-cordj encircling the outer end of the. carrier frame from chafing upon the swinging table-frame, a supporting-roller. K isjournaled in the outer swinging ends of the table-frame D to allow the cord to freely play thereover when the same is adjusting the outer end of the carrier-frame.

Secured upon the thrasher-deckB and at one side of the same is-the. bearing-bracket L, 'provided with rearwardly-extending bearing-arms I, having upon the outer endsthereof the bearing-boxes l. A short drive-shaft section M is journaled in the boxes Z and is provided at one end on one side of the thrasher- It'will be seen that by center body with the belt-pulley m, which may be connected with suitable belting for revolving said shaft, while to the other end of the shaft section M is secured the collar m. A corresponding drive-shaft N is journaled upon the top and one end of the table-frame bolster (1 upon the end thereof opposite to the bearingbracket supporting the main drive-shaft M. The said supplemental drive-shaft section N carries upon the outer end thereof the beltpullcy a, while upon the inner end thereof and terminating short of the inner end of the adjacent shaft N is secured the collar n, to which is securely fastened one end of the flexible coiled-spring coupling O,the other end of which is likewise. securely fastened to the =col1ar m ofsaid adjacent drive shaft section. -Now itwill be readily seen that. the shafts M and N'are directly connected together to form a sectional drive-shaft, so that'when theshaft M is rotated the corresponding shaft Nnismrotated therewith. Itwill alsobe apparentthat, while the said spring-coupling. serves. to directly connect the two shaftstogetherat the same time, it provides a universal coupling without the use of knuckle-joints or gearing of anykind. As the oscillating table-frame is swung. in any direction, it necessarily car- 5 ries-the shaft N. thereon, so that the sameassumes various-angles with respectto thedriv'eshaft M, which is; fixedly mounted in the-bearing-bracket L; but by the use of the coiled spring, which will bend and give to any'posi- 10o tion of the shaft N, aconnectionis provided which connects thetwo shafts firmly together and allows the same to simultaneously revolve, and: thus provides a universal coup ling, which avoids the. friction and other disadvantagesof. gearing.

Secured to the extremeou-ter end and sides of the thrasher-deck B, adjacent to said end, are the depending curtains P, havingweighted lower ends 19 and designed to inclose the delivering end of the thrasher over the lower halfv of the straw-carrier, so that the same will confinecthe wind from the fan and prevent the. same from blowing the straw and chaffotf from the carrier. The said curtains are buttoned orotherwise suitablyand removably connected to the deck of the machine, so that they may be readily removed and. placed in position when-desired. It will be observed that the side and end curtains. havetheir edges meet each other to: form an entirelyclosedspace at the outer end of'the thrasher and within the swinging frame of. the carrier attachment. No matter what. position the carrier-frame may assume the: said curtains IIK still hang in the samerelative. position to each Q is led from the said pulleys over the upper and lower pairs of guide-pulleys R, mounted at the upper and lower ends of one of the depending supporting-standards H upon one side of the swinging frame, and said upper and lower pairs of guide-pulleys are so disposed as to separate the connecting-beltQ and cause the same to follow the construction of the swinging-frame, so that the motion of the belt will be uninterrupted in whatever position the said frame may be swung or adjusted.

Now it will be readily seen from the foregoing that an improved carrier attachment for thrashing-machines is provided, which, while accomplishing all the purposes of separate carriers and stackers, at the same time provides an attachment which, on account of its improved construction and adjustments, possesses many advantages which will readily suggest themselves to those skilled in the art.

It will of course be readily understood that the several machine elements arranged in the combinations herein expressed need not necessarily be so arranged, but may be employed in various arrangements and combinations, as may be found expedient in order to accomplish the same ends, and also that any particular element or construction of such element may be used for the same purpose, as herein described in connection with other mechanical devices to secure the same result.
